DOOR-HANGER.

SPECIFICATION forming part: of Letters Patent No. 269,508, datedDecember 26, 1882.

Application filed October 27, 1882. (No model.) I

To all whom it may concern Be it known that I, FRANK BIRMINGHAM, ofHornellsville, county of Steuben, State of New York, have invented a newand useful Improvement in Door-Hangers; and I declare the following tobe a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawing, which lorms a part ofthis specification.

My invention consists in the combinations of devices and applianceshereinafter specified, and more particularlypointed out in the claim.

In the drawing the figure is a vertical section of a device embodying myinvention, with the upper wheel in elevation.

The object of my device is, first, to lessen friction in the operationof door-hangings for sliding doors; second, to prevent the door fromcrowding against the building or track, and third, to cause themechanism to work and wear evenly.

In the drawings, A represents a building; B, a door; 0, a rail or tracksecured to the building; 0, a flange or guide projecting downward fromthe track.

I) is a rigid support or bracket, adapted to be secured to the door inany proper manner.

-D is a wheel journaled into the support D at its upper end and adaptedto revolve upon the upper side of the track (3, and sustains the weightof the door.

D is a horizontal arm, projecting from the support, to which it isrigidly attached or cast solid therewith, and is placed below the flangeC.

a and a are rollers secured to the arm D and constructed to revolve in adirection at right angles with the flange C and upon either side of thesame.

b is a' cavity in the support 1) to house the roller a.

.its hanging mechanism against the track or building, converting thefriction into a rolling friction, and thwarting any tendency for themain wheel D and the track 0 to wear unevenly.

I am aware that door-hangings have heretofore been constructed with arigid support, upper wheel, and one lower wheel to operate upon theguide, as above.

The axes of the wheels a and a may be riveted to the horizontal arm Dbut I prefer to secure them in place by casting the metal of the armabout the shanks or tangs of the axes.

What I claim is A door-hanger consisting of a rigid bracket adapted tobe secured to the side of a door, and providedwith a supporting-rollerjournaled to its upper end to travel on a track, and an arm projectinglaterally from the inner side of the rigidbracket and carrying on itsupper side two wheels, which are adapted to revolve in a plane at rightangles to the supporting-roller and on opposite sides of a flangedepending from the track, substantially as shown and described.

In testimony whereof I sign this specification in the presence of twowitnesses.

FRANK BIRMINGHAM.
